通过对隐藻蓝绿藻（Cyanophora paradoxa Korschikoff）超微结构的研究表明，其胞内共生体与单细胞蓝藻关系密切。由于其特殊的栖息地，胞内共生体缺乏蓝藻特有的双层细胞壁，但被一层薄的原生质膜所包围。原生质本身分化为含有光合色素、多磷酸盐颗粒和可能的油滴的层状色质，以及具有位于中心的大的电子不透明体的非层状中心质，该中心质被含纤维的晕包围。这种晕-中心体复合体本质上可能是核的。描述了生物体的二分裂。由于这种蓝孢尚未被分类，我们将其命名为Cyanocyta korschikoffiana nov. gen. nov. sp。由于其结构的特殊性，我们发现有必要在色球藻目中为它建立一个新的科--蓝球藻科。
Studies conducted on the ultrastructure of Cyanophora paradoxa Korschikoff (a cryptomonad) have shown that its intracellular symbiont is closely related to unicellular blue-green algae. Due to its peculiar habitat, the intracellular symbiont lacks the characteristic cyanophycean double-layered cell wall, but is surrounded by a thin protoplasmic membrane. The protoplasm itself is differentiated into a lamellated chromatoplasm containing photosynthetic pigments, polyphosphate granules, and possible oil droplets, and a non-lamellar centroplasm with a large centrally located electron-opaque body surrounded by a fibril-containing halo. This halo-central body complex may be nuclear in nature. Binary fission of the organism is described. Since this cyanelle has not yet been classified, we name it Cyanocyta korschikoffiana nov. gen. nov. sp.; and because of its structural peculiarities, we find it necessary to create a new family for it, Cyanocytaceae, in the order Chroococcales.
